Here&#x27;s a comprehensive overview of DSPy concepts to guide your improvements:\n\nSignatures:\n- Signatures define tasks declaratively through input/output fields and explicit instructions.\n- They serve as blueprints for what the LM needs to accomplish.\n\nSignature Types:\n- Simple signatures: Specified as strings like &quot;input1, ..., inputN -&gt; output1, ..., outputM&quot; (e.g., &quot;topic -&gt; tweet&quot;).\n- Typed signatures: Create a subclass of dspy.Signature with a detailed docstring that includes task instructions, common pitfalls, edge cases, and successful strategies. Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5. Incorporate control flow: Add loops, conditionals, sub-modules in custom modules if the task requires iteration (e.g., multi-turn reasoning, selection, voting, etc.).\n6. Leverage LM strengths: For code-heavy tasks, define signatures with &#x27;code&#x27; outputs, extract and execute the generated code in the module&#x27;s forward pass.\n\nHere&#x27;s my current code:\n```\nimport dspy\nprogram = dspy.ChainOfThought(&quot;question -&gt; answer&quot;)\n```\n\nHere is the execution trace of the current code on example inputs, their outputs, and detailed feedback on improvements:\n```\n- Program Inputs:\n    question: What is the slope of a line perpendicular to the line whose equation\n      is $\\frac{x}4-\\frac{y}5=1$?

Here&#x27;s a comprehensive overview of DSPy concepts to guide your improvements:\n\nSignatures:\n- Signatures define tasks declaratively through input/output fields and explicit instructions.\n- They serve as blueprints for what the LM needs to accomplish.\n\nSignature Types:\n- Simple signatures: Specified as strings like &quot;input1, ..., inputN -&gt; output1, ..., outputM&quot; (e.g., &quot;topic -&gt; tweet&quot;).\n- Typed signatures: Create a subclass of dspy.Signature with a detailed docstring that includes task instructions, common pitfalls, edge cases, and successful strategies. Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5. Incorporate control flow: Add loops, conditionals, sub-modules in custom modules if the task requires iteration (e.g., multi-turn reasoning, selection, voting, etc.).\n6. Leverage LM strengths: For code-heavy tasks, define signatures with &#x27;code&#x27; outputs, extract and execute the generated code in the module&#x27;s forward pass.\n\nHere&#x27;s my current code:\n```\nimport dspy\nprogram = dspy.ChainOfThought(&quot;question -&gt; answer&quot;)\n```\n\nHere is the execution trace of the current code on example inputs, their outputs, and detailed feedback on improvements:\n```\n- Program Inputs:\n    question: An audience of $450$ people is seated in an auditorium.

Here&#x27;s a comprehensive overview of DSPy concepts to guide your improvements:\n\nSignatures:\n- Signatures define tasks declaratively through input/output fields and explicit instructions.\n- They serve as blueprints for what the LM needs to accomplish.\n\nSignature Types:\n- Simple signatures: Specified as strings like &quot;input1, ..., inputN -&gt; output1, ..., outputM&quot; (e.g., &quot;topic -&gt; tweet&quot;).\n- Typed signatures: Create a subclass of dspy.Signature with a detailed docstring that includes task instructions, common pitfalls, edge cases, and successful strategies. Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5. Incorporate control flow: Add loops, conditionals, sub-modules in custom modules if the task requires iteration (e.g., multi-turn reasoning, selection, voting, etc.).\n6.

prompt for reflection LLM:\n====================\n I am trying to solve a task using the DSPy framework. Here&#x27;s a comprehensive overview of DSPy concepts to guide your improvements:\n\nSignatures:\n- Signatures define tasks declaratively through input/output fields and explicit instructions.\n- They serve as blueprints for what the LM needs to accomplish.\n\nSignature Types:\n- Simple signatures: Specified as strings like &quot;input1, ..., inputN -&gt; output1, ..., outputM&quot; (e.g., &quot;topic -&gt; tweet&quot;).\n- Typed signatures: Create a subclass of dspy.Signature with a detailed docstring that includes task instructions, common pitfalls, edge cases, and successful strategies. Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5. Incorporate control flow: Add loops, conditionals, sub-modules in custom modules if the task requires iteration (e.g., multi-turn reasoning, selection, voting, etc.).\n6. Leverage LM strengths: For code-heavy tasks, define signatures with &#x27;code&#x27; outputs, extract and execute the generated code in the module&#x27;s forward pass.\n\nHere&#x27;s my current code:\n```\nimport dspy\nprogram = dspy.ChainOfThought(&quot;question -&gt; answer&quot;)\n```\n\nHere is the execution trace of the current code on example inputs, their outputs, and detailed feedback on improvements:\n```\n- Program Inputs:\n    question: Richard is building a rectangular playground from 200 feet of fencing.\n      The fencing must entirely enclose the playground.

The correct answer\n    is &#x27;&#x27;2500&#x27;&#x27;. Here&#x27;&#x27;s the step by step solution:\n\n    Let the length of the playground be $l$ and the width be $w$. We have the equation\n    $2l+2w=200 \\Rightarrow l + w = 100$. We want to maximize the area of this rectangular\n    playground, which is given by $lw$. From our equation, we know that $l=100-w$.\n    Substituting this in to our expression for area, we have \\[(100-w)(w)=100w-w^2\\]We\n    will now complete the square to find the maximum value of this expression. Factoring\n    a $-1$ out, we have \\[-(w^2-100w)\\]In order for the expression inside the parenthesis\n    to be a perfect square, we need to add and subtract $(100/2)^2=2500$ inside the\n    parenthesis. Doing this, we get \\[-(w^2-100w+2500-2500) \\Rightarrow -(w-50)^2+2500\\]Since\n    the maximum value of $-(w-50)^2$ is 0 (perfect squares are always nonnegative),\n    the maximum value of the entire expression is 2500, which is achieved when $w=50$\n    and $l=100-w=50$ (the playground is a square). Thus, the maximum area of the playground\n    is $\\boxed{2500}$ square feet.&#x27;\n- Program Inputs:\n    question: A triangle is formed with edges along the line $y=\\frac{2}{3}x+5$, the\n      $x$-axis, and the line $x=k$.

code, traces, and feedback to identify failure modes, strengths, and opportunities.\n- Create a concise checklist (3-7 bullets) outlining your high-level improvement plan, focusing on conceptual changes (e.g., &quot;Decompose step X into a multi-stage module&quot;).\n- Then, propose a drop-in replacement code that instantiates an improved &#x27;program&#x27; object.\n- Ensure the code is modular, efficient, and directly addresses feedback.\n- Output everything in a single code block using triple backticks—no additional explanations, comments, or language markers outside the block.\n- The code must be a valid, self-contained Python script with all necessary imports, definitions, and assignment to &#x27;program&#x27;.\n\nOutput Format:\n- Start with the checklist in plain text (3-7 short bullets).\n- Follow immediately with one code block in triple backticks containing the complete Python code, including assigning a `program` object. \n====================\n\nIteration 7:

the DSPy framework. Here&#x27;s a comprehensive overview of DSPy concepts to guide your improvements:\n\nSignatures:\n- Signatures define tasks declaratively through input/output fields and explicit instructions.\n- They serve as blueprints for what the LM needs to accomplish.\n\nSignature Types:\n- Simple signatures: Specified as strings like &quot;input1, ..., inputN -&gt; output1, ..., outputM&quot; (e.g., &quot;topic -&gt; tweet&quot;).\n- Typed signatures: Create a subclass of dspy.Signature with a detailed docstring that includes task instructions, common pitfalls, edge cases, and successful strategies. Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5. Incorporate control flow: Add loops, conditionals, sub-modules in custom modules if the task requires iteration (e.g., multi-turn reasoning, selection, voting, etc.).\n6. Leverage LM strengths: For code-heavy tasks, define signatures with &#x27;code&#x27; outputs, extract and execute the generated code in the module&#x27;s forward pass.\n\nHere&#x27;s my current code:\n```\nimport dspy\nprogram = dspy.ChainOfThought(&quot;question -&gt; answer&quot;)\n```\n\nHere is the execution trace of the current code on example inputs, their outputs, and detailed feedback on improvements:\n```\n- Program Inputs:\n    question: Of the four points $(2,2)$, $(9,11)$, $(5,7)$, and $(11,17)$, three\n      lie on the same line.

Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5. Incorporate control flow: Add loops, conditionals, sub-modules in custom modules if the task requires iteration (e.g., multi-turn reasoning, selection, voting, etc.).\n6. Leverage LM strengths: For code-heavy tasks, define signatures with &#x27;code&#x27; outputs, extract and execute the generated code in the module&#x27;s forward pass.\n\nHere&#x27;s my current code:\n```\nimport dspy\nfrom typing import Literal\n\nclass MathReasoningSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    Solve the given math word problem step by step, showing all calculations and logical deductions.\n    - For geometry problems involving points, always assign variable names to points and use coordinates in your answer.\n    - For answer extraction, provide ONLY the final answer in the required format (e.g., just the coordinate (x,y) for points, or a number for counts), with no extra explanation or restatement of the question.\n    - Common pitfalls: Do not include phrases like &#x27;The answer is...&#x27; or repeat the question.

LLM:\n====================\n I am trying to solve a task using the DSPy framework. Here&#x27;s a comprehensive overview of DSPy concepts to guide your improvements:\n\nSignatures:\n- Signatures define tasks declaratively through input/output fields and explicit instructions.\n- They serve as blueprints for what the LM needs to accomplish.\n\nSignature Types:\n- Simple signatures: Specified as strings like &quot;input1, ..., inputN -&gt; output1, ..., outputM&quot; (e.g., &quot;topic -&gt; tweet&quot;).\n- Typed signatures: Create a subclass of dspy.Signature with a detailed docstring that includes task instructions, common pitfalls, edge cases, and successful strategies. Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5.

Here&#x27;s a comprehensive overview of DSPy concepts to guide your improvements:\n\nSignatures:\n- Signatures define tasks declaratively through input/output fields and explicit instructions.\n- They serve as blueprints for what the LM needs to accomplish.\n\nSignature Types:\n- Simple signatures: Specified as strings like &quot;input1, ..., inputN -&gt; output1, ..., outputM&quot; (e.g., &quot;topic -&gt; tweet&quot;).\n- Typed signatures: Create a subclass of dspy.Signature with a detailed docstring that includes task instructions, common pitfalls, edge cases, and successful strategies. Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5. Incorporate control flow: Add loops, conditionals, sub-modules in custom modules if the task requires iteration (e.g., multi-turn reasoning, selection, voting, etc.).\n6. Leverage LM strengths: For code-heavy tasks, define signatures with &#x27;code&#x27; outputs, extract and execute the generated code in the module&#x27;s forward pass.\n\nHere&#x27;s my current code:\n```\nimport dspy\nfrom typing import Optional, Tuple\nimport re\n\nclass MathQA_Signature(dspy.Signature):\n    &quot;&quot;&quot;\n    Solve the given math problem step by step, showing all necessary reasoning and calculations.\n    - For factorization or polynomial problems, always present the answer in the exact form and order requested by the problem statement (e.g., (ax^2+bx+c)(dx^2+ex+f) with a&lt;d).\n    - Do NOT reorder factors or change the variable names or formatting from the problem&#x27;s instructions.\n    - For answers that are numbers, always express as a reduced common fraction (e.g., &#x27;25/8&#x27;), integer (e.g., &#x27;2&#x27;), or decimal (e.g., &#x27;3.5&#x27;) as appropriate.\n    - Do NOT use LaTeX, \\boxed{}, or any special formatting in the final answer—just plain text (e.g., &#x27;25/8&#x27;, &#x27;2&#x27;, &#x27;3.5&#x27;).\n    - If the answer is a fraction, reduce it to lowest terms.\n    - If the answer is negative, include the minus sign.\n    - If the answer is not a number, provide a concise, direct response in plain text.\n    - Common pitfalls: including LaTeX, boxed formatting, or extra text in the answer; not reducing fractions; misreading the question; reordering factors in polynomial answers; not following the required answer format.\n    - Edge cases: If multiple answers are possible, list all in plain text separated by commas.

Here&#x27;s a comprehensive overview of DSPy concepts to guide your improvements:\n\nSignatures:\n- Signatures define tasks declaratively through input/output fields and explicit instructions.\n- They serve as blueprints for what the LM needs to accomplish.\n\nSignature Types:\n- Simple signatures: Specified as strings like &quot;input1, ..., inputN -&gt; output1, ..., outputM&quot; (e.g., &quot;topic -&gt; tweet&quot;).\n- Typed signatures: Create a subclass of dspy.Signature with a detailed docstring that includes task instructions, common pitfalls, edge cases, and successful strategies. Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5. Incorporate control flow: Add loops, conditionals, sub-modules in custom modules if the task requires iteration (e.g., multi-turn reasoning, selection, voting, etc.).\n6. Leverage LM strengths: For code-heavy tasks, define signatures with &#x27;code&#x27; outputs, extract and execute the generated code in the module&#x27;s forward pass.\n\nHere&#x27;s my current code:\n```\nimport dspy\nimport re\nfrom typing import Optional\n\nclass MathReasoningSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    Solve the given math word problem step by step, showing all calculations and logical deductions.\n    - For geometry problems involving points, always assign variable names to points and use coordinates in your answer.\n    - For answer extraction, provide ONLY the final answer in the required format (e.g., just the coordinate (x,y) for points, or a number or reduced fraction for counts), with no extra explanation or restatement of the question.\n    - For exponent answers, output only the exponent (e.g., for &quot;10 raised to the 1/4&quot;, output &quot;\\frac{1}{4}&quot;).\n    - Common pitfalls: Do not include phrases like &#x27;The answer is...&#x27; or repeat the question. For point selection, output only the coordinate, e.g., (9,11).\n    - Edge cases: If multiple answers are possible, list all in the required format, separated by commas.\n    - Successful strategies: Use variable assignment, show all intermediate steps, and double-check calculations.\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The math word problem to solve&quot;)\n    reasoning: str = dspy.OutputField(desc=&quot;Step-by-step solution with all calculations and logic&quot;)\n\nclass MathAnswerExtractionSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    Given a detailed step-by-step solution to a math problem, extract ONLY the final answer in the required format:\n    - For coordinate answers, output only the coordinate, e.g., (9,11).\n    - For numeric answers, output only the number.\n    - For fraction answers, output as a reduced fraction in LaTeX format, e.g., &quot;\\frac{14}{3}&quot; (not (14/3), 14/3, or boxed).\n    - For exponent answers, output only the exponent, e.g., &quot;\\frac{1}{4}&quot; for &quot;10^{1/4}&quot;.\n    - Do not include any explanation, restatement, or extra text.\n    - If the reasoning contains multiple possible answers, list all in the required format, separated by commas.\n    - Common pitfalls: Do not include phrases like &#x27;The answer is&#x27;, or repeat the question.

object.\n- Ensure the code is modular, efficient, and directly addresses feedback.\n- Output everything in a single code block using triple backticks—no additional explanations, comments, or language markers outside the block.\n- The code must be a valid, self-contained Python script with all necessary imports, definitions, and assignment to &#x27;program&#x27;.\n\nOutput Format:\n- Start with the checklist in plain text (3-7 short bullets).\n- Follow immediately with one code block in triple backticks containing the complete Python code, including assigning a `program` object. \n====================\n\nIteration 15: Proposed new text for program: import dspy\nimport re\nfrom typing import List, Literal, Optional, Tuple, Union\n\n# --- Signatures ---\n\nclass MathReasoningSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    Solve the given math word problem step by step, showing all calculations and logical deductions.\n    - For geometry problems involving points, always assign variable names to points and use coordinates in your answer.\n    - For answer extraction, provide ONLY the final answer in the required format (e.g., just the coordinate (x,y) for points, or a number or reduced fraction for counts), with no extra explanation or restatement of the question.\n    - For exponent answers, output only the exponent (e.g., for &quot;10 raised to the 1/4&quot;, output &quot;\\frac{1}{4}&quot;).\n    - Common pitfalls: Do not include phrases like &#x27;The answer is...&#x27;

Here&#x27;s a comprehensive overview of DSPy concepts to guide your improvements:\n\nSignatures:\n- Signatures define tasks declaratively through input/output fields and explicit instructions.\n- They serve as blueprints for what the LM needs to accomplish.\n\nSignature Types:\n- Simple signatures: Specified as strings like &quot;input1, ..., inputN -&gt; output1, ..., outputM&quot; (e.g., &quot;topic -&gt; tweet&quot;).\n- Typed signatures: Create a subclass of dspy.Signature with a detailed docstring that includes task instructions, common pitfalls, edge cases, and successful strategies. Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5. Incorporate control flow: Add loops, conditionals, sub-modules in custom modules if the task requires iteration (e.g., multi-turn reasoning, selection, voting, etc.).\n6. Leverage LM strengths: For code-heavy tasks, define signatures with &#x27;code&#x27; outputs, extract and execute the generated code in the module&#x27;s forward pass.\n\nHere&#x27;s my current code:\n```\nimport dspy\nfrom typing import Optional, Tuple\nimport re\n\nclass MathQA_Signature(dspy.Signature):\n    &quot;&quot;&quot;\n    Solve the given math problem step by step, showing all necessary reasoning and calculations.\n    - For factorization or polynomial problems, always present the answer in the exact form and order requested by the problem statement (e.g., (ax^2+bx+c)(dx^2+ex+f) with a&lt;d).\n    - Do NOT reorder factors or change the variable names or formatting from the problem&#x27;s instructions.\n    - For answers that are numbers, always express as a reduced common fraction (e.g., &#x27;25/8&#x27;), integer (e.g., &#x27;2&#x27;), or decimal (e.g., &#x27;3.5&#x27;) as appropriate.\n    - Do NOT use LaTeX, \\boxed{}, or any special formatting in the final answer—just plain text (e.g., &#x27;25/8&#x27;, &#x27;2&#x27;, &#x27;3.5&#x27;).\n    - If the answer is a fraction, reduce it to lowest terms.\n    - If the answer is negative, include the minus sign.\n    - If the answer is not a number, provide a concise, direct response in plain text.\n    - Common pitfalls: including LaTeX, boxed formatting, or extra text in the answer; not reducing fractions; misreading the question; reordering factors in polynomial answers; not following the required answer format.\n    - Edge cases: If multiple answers are possible, list all in plain text separated by commas.

Here&#x27;s a comprehensive overview of DSPy concepts to guide your improvements:\n\nSignatures:\n- Signatures define tasks declaratively through input/output fields and explicit instructions.\n- They serve as blueprints for what the LM needs to accomplish.\n\nSignature Types:\n- Simple signatures: Specified as strings like &quot;input1, ..., inputN -&gt; output1, ..., outputM&quot; (e.g., &quot;topic -&gt; tweet&quot;).\n- Typed signatures: Create a subclass of dspy.Signature with a detailed docstring that includes task instructions, common pitfalls, edge cases, and successful strategies. Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5. Incorporate control flow: Add loops, conditionals, sub-modules in custom modules if the task requires iteration (e.g., multi-turn reasoning, selection, voting, etc.).\n6. Leverage LM strengths: For code-heavy tasks, define signatures with &#x27;code&#x27; outputs, extract and execute the generated code in the module&#x27;s forward pass.\n\nHere&#x27;s my current code:\n```\nimport dspy\nfrom typing import Optional\n\nclass MathQAReasoningSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    Solve the given math word problem step by step, showing all necessary reasoning and calculations.\n    - First, provide a clear, detailed, and logically ordered reasoning chain, using equations and algebraic steps as needed.\n    - Then, extract the final answer in the required format, strictly following these rules:\n        * If the answer should be a number, output only the number (no units, unless explicitly requested).\n        * If the answer should be an algebraic expression, output it in LaTeX math mode (e.g., \\frac{h^2}{m}).\n        * Do not include explanatory text, units, or extra formatting in the answer field unless the question explicitly requests it.\n    Common pitfalls:\n        - Including units when not required.\n        - Restating the answer with extra words or formatting.\n        - Failing to simplify expressions or extract the final answer.\n    Edge cases:\n        - If the answer is a sum or list, output only the final value(s) as required.\n        - If the answer is an expression, ensure it is fully simplified.\n    Successful strategies:\n        - Use step-by-step algebraic manipulation.\n        - Double-check the final answer for correct format and content.\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;A math word problem to solve.&quot;)\n    reasoning: str = dspy.OutputField(desc=&quot;Step-by-step solution, with equations and logic.&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Final answer, strictly in the required format (see instructions).&quot;)\n\nclass MathQAExtractSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    Given a math word problem and a detailed step-by-step solution, extract ONLY the final answer in the required format.\n    - If the answer should be a number, output only the number (no units, unless explicitly requested).\n    - If the answer should be an algebraic expression, output it in LaTeX math mode (e.g., \\frac{h^2}{m}).\n    - Do not include explanatory text, units, or extra formatting in the answer field unless the question explicitly requests it.\n    - If the answer is a sum or list, output only the final value(s) as required.\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The original math word problem.&quot;)\n    reasoning: str = dspy.InputField(desc=&quot;A detailed, step-by-step solution to the problem.&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Final answer, strictly in the required format.&quot;)\n\nclass MathQAModule(dspy.Module):\n    def __init__(self):\n        super().__init__()\n        self.reasoner = dspy.ChainOfThought(MathQAReasoningSignature)\n        self.extractor = dspy.Predict(MathQAExtractSignature)\n\n    def forward(self, question: str):\n        reasoning_pred = self.reasoner(question=question)\n        extract_pred = self.extractor(question=question, reasoning=reasoning_pred.reasoning)\n        return dspy.Prediction(\n            reasoning=reasoning_pred.reasoning,\n            answer=extract_pred.answer\n        )\n\nprogram = MathQAModule()\n```\n\nHere is the execution trace of the current code on example inputs, their outputs, and detailed feedback on improvements:\n```\n- Program Inputs:\n    question: A TV screen measures 24 by 16 inches.

step-by-step: First, deeply analyze the current code, traces, and feedback to identify failure modes, strengths, and opportunities.\n- Create a concise checklist (3-7 bullets) outlining your high-level improvement plan, focusing on conceptual changes (e.g., &quot;Decompose step X into a multi-stage module&quot;).\n- Then, propose a drop-in replacement code that instantiates an improved &#x27;program&#x27; object.\n- Ensure the code is modular, efficient, and directly addresses feedback.\n- Output everything in a single code block using triple backticks—no additional explanations, comments, or language markers outside the block.\n- The code must be a valid, self-contained Python script with all necessary imports, definitions, and assignment to &#x27;program&#x27;.\n\nOutput Format:\n- Start with the checklist in plain text (3-7 short bullets).\n- Follow immediately with one code block in triple backticks containing the complete Python code, including assigning a `program` object. \n====================\n\nIteration 18: Proposed new text for program: import dspy\nfrom typing import Literal, Optional\n\nclass MathQAReasoningSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    Solve the given math word problem step by step, showing all necessary reasoning and calculations.\n    - First, provide a clear, detailed, and logically ordered reasoning chain, using equations and algebraic steps as needed.\n    - Then, extract the final answer in the required format, strictly following these rules:\n        * If the answer is a number, output only the number (no units, unless explicitly requested).\n        * If the answer is a percent, output only the number followed by a percent sign (e.g., 44\\%).\n        * If the answer is an algebraic expression, output it in LaTeX math mode (e.g., \\frac{h^2}{m}).\n        * If the answer is a sum or list, output only the final value(s) as required.\n        * Do not include explanatory text, units, or extra formatting in the answer field unless the question explicitly requests it.\n    Common pitfalls:\n        - Omitting the percent sign for percent answers.\n        - Not wrapping expressions in LaTeX.\n        - Including explanatory text or units in the answer.\n        - Failing to simplify expressions or extract the final answer.\n    Edge cases:\n        - If the answer is a sum or list, output only the final value(s) as required.\n        - If the answer is an expression, ensure it is fully simplified and in LaTeX.\n    Successful strategies:\n        - Use step-by-step algebraic manipulation.\n        - Double-check the final answer for correct format and content.\n        - Explicitly state the answer type (number, percent, expression, sum, list) to

the DSPy framework. Here&#x27;s a comprehensive overview of DSPy concepts to guide your improvements:\n\nSignatures:\n- Signatures define tasks declaratively through input/output fields and explicit instructions.\n- They serve as blueprints for what the LM needs to accomplish.\n\nSignature Types:\n- Simple signatures: Specified as strings like &quot;input1, ..., inputN -&gt; output1, ..., outputM&quot; (e.g., &quot;topic -&gt; tweet&quot;).\n- Typed signatures: Create a subclass of dspy.Signature with a detailed docstring that includes task instructions, common pitfalls, edge cases, and successful strategies. Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5. Incorporate control flow: Add loops, conditionals, sub-modules in custom modules if the task requires iteration (e.g., multi-turn reasoning, selection, voting, etc.).\n6. Leverage LM strengths: For code-heavy tasks, define signatures with &#x27;code&#x27; outputs, extract and execute the generated code in the module&#x27;s forward pass.\n\nHere&#x27;s my current code:\n```\nimport dspy\nfrom typing import Optional, Tuple\nimport re\n\nclass MathQA_Signature(dspy.Signature):\n    &quot;&quot;&quot;\n    Solve the given math problem step by step, showing all necessary reasoning and calculations.\n    - For factorization or polynomial problems, always present the answer in the exact form and order requested by the problem statement (e.g., (ax^2+bx+c)(dx^2+ex+f) with a&lt;d).\n    - Do NOT reorder factors or change the variable names or formatting from the problem&#x27;s instructions.\n    - For answers that are numbers, always express as a reduced common fraction (e.g., &#x27;25/8&#x27;), integer (e.g., &#x27;2&#x27;), or decimal (e.g., &#x27;3.5&#x27;) as appropriate.\n    - Do NOT use LaTeX, \\boxed{}, or any special formatting in the final answer—just plain text (e.g., &#x27;25/8&#x27;, &#x27;2&#x27;, &#x27;3.5&#x27;).\n    - If the answer is a fraction, reduce it to lowest terms.\n    - If the answer is negative, include the minus sign.\n    - If the answer is not a number, provide a concise, direct response in plain text.\n    - Common pitfalls: including LaTeX, boxed formatting, or extra text in the answer; not reducing fractions; misreading the question; reordering factors in polynomial answers; not following the required answer format.\n    - Edge cases: If multiple answers are possible, list all in plain text separated by commas.

For factorization, always respect the order and format requested (e.g., a&lt;d).\n    - Successful strategy: Show all work in &#x27;reasoning&#x27;, then clearly state the final answer in the required

Here&#x27;s a comprehensive overview of DSPy concepts to guide your improvements:\n\nSignatures:\n- Signatures define tasks declaratively through input/output fields and explicit instructions.\n- They serve as blueprints for what the LM needs to accomplish.\n\nSignature Types:\n- Simple signatures: Specified as strings like &quot;input1, ..., inputN -&gt; output1, ..., outputM&quot; (e.g., &quot;topic -&gt; tweet&quot;).\n- Typed signatures: Create a subclass of dspy.Signature with a detailed docstring that includes task instructions, common pitfalls, edge cases, and successful strategies. Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5. Incorporate control flow: Add loops, conditionals, sub-modules in custom modules if the task requires iteration (e.g., multi-turn reasoning, selection, voting, etc.).\n6. Leverage LM strengths: For code-heavy tasks, define signatures with &#x27;code&#x27; outputs, extract and execute the generated code in the module&#x27;s forward pass.\n\nHere&#x27;s my current code:\n```\nimport dspy\nfrom typing import Optional\n\nclass MathQAReasoningSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    Solve the given math word problem step by step, showing all necessary reasoning and calculations.\n    - First, provide a clear, detailed, and logically ordered reasoning chain, using equations and algebraic steps as needed.\n    - Then, extract the final answer in the required format, strictly following these rules:\n        * If the answer should be a number, output only the number (no units, unless explicitly requested).\n        * If the answer should be an algebraic expression, output it in LaTeX math mode (e.g., \\frac{h^2}{m}).\n        * Do not include explanatory text, units, or extra formatting in the answer field unless the question explicitly requests it.\n    Common pitfalls:\n        - Including units when not required.\n        - Restating the answer with extra words or formatting.\n        - Failing to simplify expressions or extract the final answer.\n    Edge cases:\n        - If the answer is a sum or list, output only the final value(s) as required.\n        - If the answer is an expression, ensure it is fully simplified.\n    Successful strategies:\n        - Use step-by-step algebraic manipulation.\n        - Double-check the final answer for correct format and content.\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;A math word problem to solve.&quot;)\n    reasoning: str = dspy.OutputField(desc=&quot;Step-by-step solution, with equations and logic.&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Final answer, strictly in the required format (see instructions).&quot;)\n\nclass MathQAExtractSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    Given a math word problem and a detailed step-by-step solution, extract ONLY the final answer in the required format.\n    - If the answer should be a number, output only the number (no units, unless explicitly requested).\n    - If the answer should be an algebraic expression, output it in LaTeX math mode (e.g., \\frac{h^2}{m}).\n    - Do not include explanatory text, units, or extra formatting in the answer field unless the question explicitly requests it.\n    - If the answer is a sum or list, output only the final value(s) as required.\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The original math word problem.&quot;)\n    reasoning: str = dspy.InputField(desc=&quot;A detailed, step-by-step solution to the problem.&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Final answer, strictly in the required format.&quot;)\n\nclass MathQAModule(dspy.Module):\n    def __init__(self):\n        super().__init__()\n        self.reasoner = dspy.ChainOfThought(MathQAReasoningSignature)\n        self.extractor = dspy.Predict(MathQAExtractSignature)\n\n    def forward(self, question: str):\n        reasoning_pred = self.reasoner(question=question)\n        extract_pred = self.extractor(question=question, reasoning=reasoning_pred.reasoning)\n        return dspy.Prediction(\n            reasoning=reasoning_pred.reasoning,\n            answer=extract_pred.answer\n        )\n\nprogram = MathQAModule()\n```\n\nHere is the execution trace of the current code on example inputs, their outputs, and detailed feedback on improvements:\n```\n- Program Inputs:\n    question: If we express $x^2 + 4x + 5$ in the form $a(x - h)^2 + k$, then what\n      is $h$?\n  Program Outputs:\n    reasoning: &quot;To express the quadratic \\\\( x^2 + 4x + 5 \\\\) in the form \\\\( a(x\\\n      \\ - h)^2 + k \\\\), we need to complete the square.\\n\\n1.

The correct answer\n    is &#x27;&#x27;-\\sqrt{x-3}+3&#x27;&#x27;. Here&#x27;&#x27;s the step by step solution:\n\n    Notice that since the linear term of the quadratic is $-6,$ the vertex of the\n    parabola that is the left side of $f$ is at $x=3.$ Therefore it might help to\n    complete the square. \\[x^2-6x+12=(x^2-6x+9)+3=(x-3)^2+3.\\]We want to have that\n    $f(f(x))=x$ for every $x.$ Since $f(f(3))=3,$ we know $f$ is its own inverse at\n    $x=3,$ so we can restrict our attention to $x\\neq 3.$\n\n\n    Since $f$ applied to any number less than $3$ returns a number greater than $3,$\n    and we can get all numbers greater than $3$ this way, applying $f$ to any number\n    greater than $3$ must give a number less than $3.$ Therefore $k(x)&lt;3$ for any\n    $x&gt;3.$\n\n\n    If $x&gt;3$ and $f$ is its own inverse then \\[x=f(f(x))=f(k(x))=3+\\left(k(x)-3\\right)^2,\\]where\n    in the last step we used that $k(x)&lt;3.$ Subtracting $3$ from both sides gives\n    \\[\\left(k(x)-3\\right)^2 = x-3.\\]Since we must have $k(x) &lt; 3,$ we know that $k(x)\n    - 3$ is the negative number whose square is $x-3.$ Therefore, we have $k(x) -\n    3 = -\\sqrt{x-3}.$ Solving this for $k(x)$ gives  \\[k(x)=\\boxed{-\\sqrt{x-3}+3}.\\]&#x27;\n\n```\n\nAssignment:\n- Think step-by-step: First, deeply analyze the current code, traces, and feedback to identify failure modes, strengths, and opportunities.\n- Create a concise checklist (3-7 bullets) outlining your high-level improvement plan, focusing on conceptual changes (e.g., &quot;Decompose step X into a multi-stage module&quot;).\n- Then, propose a drop-in replacement code that instantiates an improved &#x27;program&#x27; object.\n- Ensure the code is modular, efficient, and directly addresses feedback.\n- Output everything in a single code block using triple backticks—no additional explanations, comments, or language markers outside the block.\n- The code must be a valid, self-contained Python script with all necessary imports, definitions, and assignment to &#x27;program&#x27;.\n\nOutput Format:\n- Start with the checklist in plain text (3-7 short bullets).\n- Follow immediately with one code block in triple backticks containing the complete Python code, including assigning a `program` object. \n====================\n\nIteration 27: Proposed new text for program: import dspy\nimport re\nfrom typing import Optional\n\nclass MathQAReasoningSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    Solve the given math word problem step by step, showing all necessary reasoning and calculations.\n    - First, provide a clear, detailed, and logically ordered reasoning chain, using equations and algebraic steps as needed.\n    - Then, extract the final answer in the required format, strictly following these rules:\n        * If the answer should be a number, output only the number (no units, unless explicitly requested).\n        * If the answer should be an algebraic expression, output it in LaTeX math mode (e.g., \\\\frac{h^2}{m}).\n        * If the answer involves a square root or multiple branches, select the correct branch based on domain restrictions and problem context.

Here&#x27;s a comprehensive overview of DSPy concepts to guide your improvements:\n\nSignatures:\n- Signatures define tasks declaratively through input/output fields and explicit instructions.\n- They serve as blueprints for what the LM needs to accomplish.\n\nSignature Types:\n- Simple signatures: Specified as strings like &quot;input1, ..., inputN -&gt; output1, ..., outputM&quot; (e.g., &quot;topic -&gt; tweet&quot;).\n- Typed signatures: Create a subclass of dspy.Signature with a detailed docstring that includes task instructions, common pitfalls, edge cases, and successful strategies. Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5. Incorporate control flow: Add loops, conditionals, sub-modules in custom modules if the task requires iteration (e.g., multi-turn reasoning, selection, voting, etc.).\n6. Leverage LM strengths: For code-heavy tasks, define signatures with &#x27;code&#x27; outputs, extract and execute the generated code in the module&#x27;s forward pass.\n\nHere&#x27;s my current code:\n```\nimport dspy\nimport re\nfrom typing import List, Literal, Optional, Tuple, Union\n\n# --- Signatures ---\n\nclass MathReasoningSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    Solve the given math word problem step by step, showing all calculations and logical deductions.\n    - For geometry problems involving points, always assign variable names to points and use coordinates in your answer.\n    - For answer extraction, provide ONLY the final answer in the required format (e.g., just the coordinate (x,y) for points, or a number or reduced fraction for counts), with no extra explanation or restatement of the question.\n    - For exponent answers, output only the exponent (e.g., for &quot;10 raised to the 1/4&quot;, output &quot;\\frac{1}{4}&quot;).\n    - Common pitfalls: Do not include phrases like &#x27;The answer is...&#x27; or repeat the question.

LLM:\n====================\n I am trying to solve a task using the DSPy framework. Here&#x27;s a comprehensive overview of DSPy concepts to guide your improvements:\n\nSignatures:\n- Signatures define tasks declaratively through input/output fields and explicit instructions.\n- They serve as blueprints for what the LM needs to accomplish.\n\nSignature Types:\n- Simple signatures: Specified as strings like &quot;input1, ..., inputN -&gt; output1, ..., outputM&quot; (e.g., &quot;topic -&gt; tweet&quot;).\n- Typed signatures: Create a subclass of dspy.Signature with a detailed docstring that includes task instructions, common pitfalls, edge cases, and successful strategies. Define fields using dspy.InputField(desc=&quot;...&quot;, type=...) and dspy.OutputField(desc=&quot;...&quot;, type=...) with pydantic types such as str, List[str], Literal[&quot;option1&quot;, &quot;option2&quot;], or custom classes.\n\nModules:\n- Modules specify __how__ to solve the task defined by a signature.\n- They are composable units inspired by PyTorch layers, using language models to process inputs and produce outputs.\n- Inputs are provided as keyword arguments matching the signature&#x27;s input fields.\n- Outputs are returned as dspy.Prediction objects containing the signature&#x27;s output fields.\n- Key built-in modules:\n  - dspy.Predict(signature): Performs a single LM call to directly generate the outputs from the inputs.\n  - dspy.ChainOfThought(signature): Performs a single LM call that first generates a reasoning chain, then the outputs (adds a &#x27;reasoning&#x27; field to the prediction).\n  - Other options: dspy.ReAct(signature) for reasoning and acting, or custom chains.\n- Custom modules: Subclass dspy.Module. In __init__, compose sub-modules (e.g., other Predict or ChainOfThought instances). In forward(self, **kwargs), define the data flow: call sub-modules, execute Python logic if needed, and return dspy.Prediction with the output fields.\n\nExample Usage:\n```\n# Simple signature\nsimple_signature = &quot;question -&gt; answer&quot;\n\n# Typed signature\nclass ComplexSignature(dspy.Signature):\n    &quot;&quot;&quot;\n    &lt;Detailed instructions for completing the task: Include steps, common pitfalls, edge cases, successful strategies. Include domain knowledge...&gt;\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;The question to answer&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Concise and accurate answer&quot;)\n\n# Built-in module\nsimple_program = dspy.Predict(simple_signature)  # or dspy.ChainOfThought(ComplexSignature)\n\n# Custom module\nclass ComplexModule(dspy.Module):\n    def __init__(self):\n        self.reasoner = dspy.ChainOfThought(&quot;question -&gt; intermediate_answer&quot;)\n        self.finalizer = dspy.Predict(&quot;intermediate_answer -&gt; answer&quot;)\n    \n    def forward(self, question: str):\n        intermediate = self.reasoner(question=question)\n        final = self.finalizer(intermediate_answer=intermediate.intermediate_answer)\n        return dspy.Prediction(answer=final.answer, reasoning=intermediate.reasoning) # dspy.ChainOfThought returns &#x27;reasoning&#x27; in addition to the signature outputs.\n\ncomplex_program = ComplexModule()\n```\n\nDSPy Improvement Strategies:\n1. Analyze traces for LM overload: If a single call struggles (e.g., skips steps or hallucinates), decompose into multi-step modules with ChainOfThought or custom logic for stepwise reasoning.\n2. Avoid over-decomposition: If the program is too fragmented, consolidate related steps into fewer modules for efficiency and coherence.\n3. Refine signatures: Enhance docstrings with actionable guidance from traces—address specific errors, incorporate domain knowledge, document edge cases, and suggest reasoning patterns. Ensure docstrings are self-contained, as the LM won&#x27;t have access external traces during runtime.\n4. Balance LM and Python: Use Python for symbolic/logical operations (e.g., loops, conditionals); delegate complex reasoning or generation to LM calls.\n5. Incorporate control flow: Add loops, conditionals, sub-modules in custom modules if the task requires iteration (e.g., multi-turn reasoning, selection, voting, etc.).\n6. Leverage LM strengths: For code-heavy tasks, define signatures with &#x27;code&#x27; outputs, extract and execute the generated code in the module&#x27;s forward pass.\n\nHere&#x27;s my current code:\n```\nimport dspy\nfrom typing import Optional, Tuple\nimport re\n\nclass MathQA_Signature(dspy.Signature):\n    &quot;&quot;&quot;\n    Solve the given math problem step by step, showing all necessary reasoning and calculations.\n    - For factorization or polynomial problems, always present the answer in the exact form and order requested by the problem statement (e.g., (ax^2+bx+c)(dx^2+ex+f) with a&lt;d).\n    - Do NOT reorder factors or change the variable names or formatting from the problem&#x27;s instructions.\n    - For answers that are numbers, always express as a reduced common fraction (e.g., &#x27;25/8&#x27;), integer (e.g., &#x27;2&#x27;), or decimal (e.g., &#x27;3.5&#x27;) as appropriate.\n    - Do NOT use LaTeX, \\boxed{}, or any special formatting in the final answer—just plain text (e.g., &#x27;25/8&#x27;, &#x27;2&#x27;, &#x27;3.5&#x27;).\n    - If the answer is a fraction, reduce it to lowest terms.\n    - If the answer is negative, include the minus sign.\n    - If the answer is not a number, provide a concise, direct response in plain text.\n    - Common pitfalls: including LaTeX, boxed formatting, or extra text in the answer; not reducing fractions; misreading the question; reordering factors in polynomial answers; not following the required answer format.\n    - Edge cases: If multiple answers are possible, list all in plain text separated by commas. For factorization, always respect the order and format requested (e.g., a&lt;d).\n    - Successful strategy: Show all work in &#x27;reasoning&#x27;, then clearly state the final answer in the required format in &#x27;answer&#x27;, matching the problem&#x27;s requested form exactly.\n    &quot;&quot;&quot;\n    question: str = dspy.InputField(desc=&quot;A math problem to solve&quot;)\n    reasoning: str = dspy.OutputField(desc=&quot;Step-by-step solution and justification&quot;)\n    answer: str = dspy.OutputField(desc=&quot;Final answer in plain text, matching the required format and order&quot;)\n\nclass MathQAPostProcess(dspy.Module):\n    def __init__(self):\n        self.cot = dspy.ChainOfThought(MathQA_Signature)\n\n    def _is_factorization_problem(self, question: str) -&gt; bool:\n        # Heuristic: look for &quot;factor&quot;, &quot;polynomial&quot;, &quot;form (&quot;, etc.\n        return bool(re.search(r&#x27;\\bfactor\\b|\\bpolynomial\\b|form\\s*\\(&#x27;, question, re.IGNORECASE))\n\n    def _extract_factors(self, answer: str) -&gt; Optional[Tuple[str, str]]:\n        # Try to extract two quadratic factors in the form (ax^2+bx+c)(dx^2+ex+f)\n        m = re.match(r&#x27;\\(?([-\\d\\w^+* ]+)\\)?\\(?([-\\d\\w^+* ]+)\\)?&#x27;, answer.replace(&#x27; &#x27;, &#x27;&#x27;))\n        if m:\n            # Try to split at the first &#x27;)(&#x27;\n            parts = re.split(r&#x27;\\)\\s*\\(&#x27;, answer)\n            if len(parts) == 2:\n                left = parts[0].lstrip(&#x27;(&#x27;)\n                right = parts[1].rstrip(&#x27;)&#x27;)\n                return left, right\n        # Try to match ( ... )( ... )\n        m = re.match(r&#x27;\\(([^)]+)\\)\\(([^)]+)\\)&#x27;, answer.replace(&#x27; &#x27;, &#x27;&#x27;))\n        if m:\n            return m.group(1), m.group(2)\n        return None\n\n    def _enforce_order(self, answer: str, question: str) -&gt; str:\n        # Only applies to factorization problems with explicit order (e.g., a&lt;d)\n        # Try to extract the order requirement\n        order_match = re.search(r&#x27;form.*\\(([^)]+)\\)\\(([^)]+)\\).*a&lt;d&#x27;, question.replace(&#x27; &#x27;, &#x27;&#x27;), re.IGNORECASE)\n        if not order_match:\n            return answer\n        # Try to extract factors\n        factors = self._extract_factors(answer)\n        if not factors:\n            return answer\n        left, right = factors\n        # Extract leading coefficients\n        def leading_coeff(expr):\n            m = re.match(r&#x27;([+-]?\\d*)x\\^2&#x27;, expr)\n            if m:\n                s = m.group(1)\n                if s in (&#x27;&#x27;, &#x27;+&#x27;):\n                    return 1\n                elif s == &#x27;-&#x27;:\n                    return -1\n                else:\n                    try:\n                        return int(s)\n                    except Exception:\n                        return None\n            return None\n        a = leading_coeff(left)\n        d = leading_coeff(right)\n        if a is not None and d is not None and a &gt; d:\n            # Swap to enforce a&lt;d\n            return f&quot;({right})({left})&quot;\n        return answer\n\n    def forward(self, question: str):\n        pred = self.cot(question=question)\n        answer = pred.answer.strip()\n        # Post-process for factorization problems\n        if self._is_factorization_problem(question):\n            answer = self._enforce_order(answer, question)\n        return dspy.Prediction(reasoning=pred.reasoning, answer=answer)\n\nprogram = MathQAPostProcess()\n```\n\nHere is the execution trace of the current code on example inputs, their outputs, and detailed feedback on improvements:\n```\n- Program Inputs:\n    question: A man nearing retirement wants to invest some money in a fund that compounds\n      annually at a rate of 6 percent, so that in five years, he will have at least\n      $\\$100,000$.

For factorization, always respect the order and format requested (e.g., a&lt;d), and match the use of parentheses to the question or provided factors.\n    - Successful strategy: Show all work in
